In my experience, just a dab of Permatex anti-seize on each rail bolt, and say goodbye to junk T-nuts. Really helps when you know that you are the guy that will be doing all the work in the future.
I’ve Watched several of your videos now. Full of great advice. I just bought a bar box table, that has scratches in the slate. ( sat without any cloth on it, and it appears furniture was stored on top of it. ) love to see a video on how you would correct that situation.
